1.	Which of the following ways of cooling is used for the maintaining of die temperature?(a) Natural air cooling(b) Forced air cooling(c) Water channels cooling(d) Liquid nitrogen coolingThe question was posed to me during an online interview.My doubt stems from Die Casting in portion Special Casting Techniques of Casting-Forming-Welding I
Answer» The correct choice is (C) Water channels cooling The explanation is: As the metallic die is used in the die casting as a mould, so the extraction of heat from the molten metal will not be easy. So for maintaining PROPER die TEMPERATURE, water cooling channels are used near the castings through the COVER and ejector die. This makes the proper solidification of the castings.
